My organization has a project that is using Google Drive to store files. What we want to do is to show the contents of the Drive on a website.
I'm not really sure how to go about this. Most of the examples are showing authenticating the user accessing the site.
Right now, what I am thinking of doing is to use a service account. I have a Node app running a service account, which I just followed from the samples in the Node.js samples. I realized that the contents shown from running the app are the contents of the Drive of the service account.
What I wanted to happen was show the contents of the Drive that owns the project.
I'm not sure if you can get around authentication when it comes to standard User Accounts.
But you don't really need to impersonate a User Account. There is a alternative solution. From your User account, create a folder and move all the files needed by the app into it. Then share the folder with the service account and grant it edit access. To share the folder you'll need to know the email address of the service account which you can find in your Google Developer's Console. To get to the service account's page, click the menu icon (the triple bar) at the top left and select IAM Admin. On that page there should be a menu option for service accounts, when selected it will provide you with a list of all your service accounts and their corresponding email addresses.

How to test safely an app that reads and writes to Google Drive using the API?
I created an app that runs on a server, that basically copies a template google doc to another directory, and then edits this new file.
In order to do that I:
created a service account,
delegated domain-wide authority to this service account
(https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority),
Then the app impersonates a user of the domain (always the same user) to access the API resources.
This app works, but it has 2 problems:
the service account has access to too many things. Ideally, I'd like it to have RW access to one folder only,
I'd like to create test credentials that would have access to another specific folder only, or even better, another drive.
Thanks!
Drive does not have permissions based on folders. The closest you can get is by creating an additional Service Account and then share the folder(s) to that SA.
You can also change the sharing setting for just one organisational unit,doing that all the folders whose owners are part of that OU will be able to share it outside or your domain making that the SA have only access to those folders.
I have created a web app which is making use of Google Drive API/ REST v2 (https://developers.google.com/drive/v2/web/about-sdk) to perform actions such as create/update/rename/delete of documents etc.
I am authorizing requests with OAuth 2.0 (client side - that means every access token is valid for ~1h and then silently I am getting a new token) and then perform previous actions using that token.
I have a new requirement for the authorized user to share his/her documents for writing/updating them (I found out that API has option for inserting permissions (https://developers.google.com/drive/v2/reference/permissions/insert : role: writer, type: anyone).
Is it possible for a non-authenticated user to be able to write/update documents (programmatically - via Google Drive API v2 or another API?) that have been created from the authenticated user that shared these? (something that is similar to google docs/ sharing when a user is sharing his document and offline users are able to edit it?
Thanks.

What you are describing here is something called a service account. Service accounts are like dummy users. You can share a file on your Google drive account with the service accounts email address and the service account will then have access to that file. Assuming that you gave them edit permissions it will be able to read and write to it without authenticating.
Note: service accounts do not work client sided you will need to use a server sided language to use service accounts.
I have created a service account for use with the Google Drive API as outlined here:
https://developers.google.com/drive/delegation
After all the reading I've done, my impression is that this service account should act on behalf of the actual account which is part of the Google Apps for Business domain being used.
With that, I would expect that no special permissions would be needed to be dealt with when dealing with Google Drive folders. However, after authenticating and trying to list the contents of a folder, nothing is shown.
If I add the service account email address specifically to the "share" list for the folder, everything seems to work as intended. I can list the files in the folder using the API.
My question is, is this the way it's supposed to be or am I missing something that would allow the service account to access folders on behalf of the actual account without having to specifically add the service account email address to the share list?
Thank you for your time.
You need to impersonate the user with his/her email. Go through the steps explained on https://developers.google.com/drive/delegation and use the snippets below for further coding reference.
We have a google corporate account and need to transfer ALL of a user's google drive files to another account in certain instances. We want to do what is described at the following link for "all files" but programatically via the latest Drive API http://support.google.com/a/bin/answer.py?hl=en&answer=1247799
We are currently using the following API version(s) below, coupled with domain wide authority delegation as described at https://developers.google.com/drive/delegation and are able to see a user's files, iterate over them etc.
google-api-services-drive 1.14.2-beta
google-api-client 1.14.1-beta
My question is this: it appears that the only way to change permissions is by fileId by fileId etc. Instead of having to traverse and iterate over an entire set of user's files, if we just want to transfer ALL of a user's files to another particular user: is there a way in the API to do this (ownership transfer for ALL files) rather than individual requests file/by file?
Also when transferring ownershisp, must the transferee be in the same #domain or can it be another #domain we manage? I read somewhere that you can only transfer to owners in the same domain. Does this still hold true? For instance we manage #myCompany.com and have our corporate account registered under that, however that shell account has several sub-domains within it. We would like to transfer files from users in the sub-domains to a central user in the #myCompany domain.
You need to change permissions file by file, there is no updateAll type of functionality at the moment.
You cant transfer the ownership to another domain's user. Ownership can only be transferred to another user in the same domain as the current owner.
This answer doesn't directly answer your question, but it could be helpful for both you and future visitors.
As of now, you can mass transfer files to new users with Google's new Admin console. It doesn't let you filter for specific folders, but it does allow you to transfer all of one user's Drive files to a second user.
I know you were trying to create something which uses the API to iterate through folders and files, and you probably have a very specific use-case in mind. However, in the case where you have employees leaving, or you need to transfer everything, using the following method is fast and simple.
Open the Google Admin console
Go to Google Apps > Drive
Click on "Transfer ownership"
Fill out both user fields and submit
This process will even email both users once the process is completed.
You can do this with a single call to the Data Transfer API
Exactly what is needed but only with API!
Open the Google Admin console
Go to Google Apps > Drive
Click on "Transfer ownership"
Fill out both user fields and submit
This process will even email both users once the process is completed.
If this is not possible via API calls, then there is no point deleting a user using API.
I have a web app in php mysql, I want to use one google drive account for my app.
Can I use my app's accounts instead of google users for privilages.
I read in SDK I can use service account to login without promting user, but I don't know how to share or give permissions files for custom users.
In api reference I found this:
"The user is not necessarily yet a Google user (e.g. if a file or folder is shared with an email address that does not yet have an associated Google account). Example: 1111459233037698895607".
How a custom user in my app should get a token for own privilages.
I am not exactly sure what you want to achieve here, but if you want to use your own permission system, you can't. You can, however, apply read/write/owner permissions to files to mirror your own permissions.
If I have totally got the wrong idea, please explain.
